I’ve got a dremel and a die grinder, don’t think I’ve got a small enough burr but it’s worth a go. Thinking about it, somewhere I’ve got a dremel drill press, that’d keep it all nice and straight, hmmmm worth trying on some scrap bearings first.
Any suggestions on how I’d best make a 2.5mm wide hole approx 3mm deep in a bearing race? I do have a super 7 and a decent pillar drill. Really don’t want to get much heat into it though.
I think if it’s a good fit on what you’re using to hammer down the middle then grease works ok, it tends to squidge out though if it’s not a foot fit. I thought the bread might try and come back through the rollers but it didn’t.
We use similar stuff to dynamat in automotive, it’s actually durable enough to last whole vehicle life while subjected to the temperature and vibration stresses that that generates. Might be a different story subjecting it to a whole load of super low frequency high amplitude energy. I don’t...
Anyone had any luck with small internal bearing pullers? I’ve got one to remove from a blind hole in a casing.

So not a heap of...
It’s usual to try and deaden with something ‘soft’ like a ‘constrained layer mass damping material’ which is the black sticky stuff with foil on it. That’s used widely in automotive and audio applications.
So I managed to find a ‘used once’ whale kit for 90 quid which seemed sensible. It works well enough, they don’t have a tool specifically for hollow type rivets but they seem to stake enough anyway.
